Cam position sensor issue

Has anyone had any experience with this? My indy read the fault code and told me I should bring the car to the dealer (I set up an appointment for wednesday). What might be causing this fault code? The actual fault was:
"PO344- Cam Position Sensor A, B1"

Thanks for the help.

Being that the code was for the cam sensor and the fact that cam sensors are always failing on these cars; I would not be surprised at all if the cam sensor was your problem.

from what I understand it takes about 20 minutes to DIY and the part is a little over $100 iirc. Ill see if I can find a DIY writeup for you. dont waste your $$ taking it to the dealer for this, thats definately not necessary. Im really surprised your indy told you to take it to BMW...

It's not that difficult to replace yourself but it somewhat depends on your car (V-8 or I-6). First you need to make sure you know whether the bad unit is on the intake or exhaust side (you have one for each). The intake CPS is harder on the I-6 because you have to remove some of the air intake pieces to get to the sensor and connector. The exhaust is easier. I think both are fairly easy on the V-8's.

Good luck.

I cant find a writeup for a 530 yet, but I did read that the I6's sensor is in the same spot as the V8. if nothing else you could look at the 540 DIY and open up your hood and see if the sensor is there on yours too.

www.bmwtips.com ...its #23 under "Engine Trans & Exhaust"

good luck, and Ill keep looking for an I6 diy writeup

On the double-vanos I-6, the intake cam sensor is behind one of the vanos solenoids, and that needs to be removed to access the cam sensor. The exhaust cam sensor is accessible without removing anything. The screws holding the sensors in place require allen keys or allen sockets. The solenoid unscrews and requires a large open end wrench (22mm, something like that). The hardest part is unplugging the wiring harness from the sensors, so this is not too bad of a DIY project if you're looking to save some cash. The sensors themselves are about $100 a piece, give or take. I think the o-rings for the sensors are sold seperately, and the new sensors do not come with any. The old ones, however, can be reused in a pinch.
